为了解HR-EPS模块剪力墙结构在低周反复作用下的抗震性能,通过选取配筋率及边缘约束构件两种控制因素对HR-EPS模块剪力墙进行低周反复加载试验,以此定位此剪力墙的抗震性能。试验结果表明:高宽比为1.63的所有模块剪力墙以剪切破坏为主;对于配筋率较大和设置有边缘约束构件的墙体,钢筋的加强作用可以提高墙体的整体刚度,约束裂缝的弥散,提高承载能力,位移延性增幅不太明显。通过试验数据分析对比得出HR-EPS模块剪力墙的抗震性能类似于保温砌模现浇承重体系,略高于保温砌模格构式墙体。
In order to understand the seismic performance of HR-EPS modular shear wall structure with low-cycle repetition, the low-cycle loading test of HR-EPS modular shear wall was carried out by selecting the control factors of the ratio of reinforcement and the edge restraining member. Positioning the seismic performance of the shear wall. The test results show that all the shear walls with module with aspect ratio of 1.63 are mainly shear failure. For reinforced walls and reinforced concrete walls with reinforced reinforcement, the reinforcement can increase the overall stiffness of the wall, The dispersion of cracks, improve the carrying capacity, displacement ductility less obvious. Through the analysis and comparison of the test data, it is concluded that the seismic performance of the shear wall of HR-EPS module is similar to the cast-in-place load-bearing system of thermal insulation mold, which is slightly higher than that of thermal insulation.
